Question 1.
Why are the levels of all the seas equal in the world?
Answer:
Since all seas in the world are connected to each other, the levels of all the seas all over the world are roughly the same.
Question 2.
How is the sea level measured?
Answer:
- There are high tides and low tides on the level of the sea, and they never stand still.
- As a result of this phenomenon, the level of the sea keeps on either rising or falling.
- The level of the sea is carefully measured at frequent intervals and the mean level of the sea is calculated.
- Over a period of time, scientists observe the high and low levels of the sea and they calculate average level which is known as Mean Sea Level (MS.L.)
Question 3.
What are the uses of maps showing height?
Answer:
- Maps showing height help us to understand the nature of the terrain, where the mountains are, where the valleys are etc. For example: If you look at the physical map of Telangana, you can identify the Godavari slopes in the Eastern part.
- Maps showing height are very essential to construct roads or dams.
Question 4.
What differences do you find between the lifestyle of people living on high altitudes and low altitudes?
Answer:
| The lifestyle of people living in high altitudes | The lifestyle of people living in low altitudes |

How are maps helpful to people?
Answer:
- Maps are helpful to know where the mountains are, where the valleys are, and to understand the nature of the terrain etc.
- Maps are essential when roads or dams have to be constructed.
- Maps are useful to study and understand the geographical conditions of any place.
- Historical maps are useful to know the history of any country through ages.
- Political maps tell us the boundaries of the continents, countries, states, and districts, etc.
- Maps help to identify the places and their routes.
Question 6.
Read the para Contour Lines’ of page 5 and comment on it.
Contour Lines:
A contour is a line joining the places with equal heights. On the map of Nimpur, you would have seen that there is a line passing through the village, this is the 50-meter contour line. All places on this line will have the same height of 50 meters, Contour lines will be in irregular shape depending upon the landform. These cannot cut with each other.
The distance between two contour lines will depend upon the landscape. If the laud has a steep climb then tile contour lines will be near to each other, if the slope of tile land is gentle, then the contour lines will be quite far from each other.

Question 4.
In class VI you have learnt to measure distances between places with the help of the ‘scale’ given in the map. Now try to find out the distance between Hyderabad and various state capitals like Jaipur, Imphal, Gandhinagar, and Thiruvananthapuram.
Answer:
The relationship between a distance on the map and corresponding distance on the ground is shown with the help of the Scale’.
For example. 1 centimeter = 200 kilometers
i) The distance between Hyderabad and Jaipur is 6 cm.
6 cm x 200 km = 1200 km.
ii) The distance between Hyderabad and Imphal is 9 cm.
9 x 200 km = 1800 km.
iii) The distance between Hyderabad and Gandhinagar is 5 cm.
5 cm x 200 km = 1000 km.
iv) The distance between Hyderabad and Thiruvananthapuram is 5.5 cm.
5 ½ cm X 200 km = 1100 km.

Reading text (given), understanding and interpretation)
Mean Sea Level
There are high tides and low tides on the level of the sea, and they never stand still. As a result of this phenomenon, the level of the sea keeps on either rising or falling. Which of these heights do we take as the sea level or 0-meter height? In order to solve this problem the level of the sea is carefully measured at frequent intervals and the mean level of the sea is calculated. Over a period scientists observed the high and low levels of the sea and they have come to one calculated average level which is known as Mean Sea Level (M.S.L).
Question.
What do you mean by Mean Sea [eve!?
Answer:
- The level of the sea keeps on either rising or falling due to high tides and low tides.
- To solve this problem the level of the sea is carefully measured at frequent intervals.
- Over a period of time, scientists observed and calculated average level.
- That calculated average sea level is known as the Mean Sea Level (M.S.L). Reflection on contemporary issues and questioning
Question.
Why should we study the different kinds of maps?
Answer:
Maps tell us about the location of different places. They are used to show the hot and cool places, how much rainfall the places receive. The maps also tell us the places in which different crops are grown and having different kinds of forests. So, we should study the different kinds of maps.
